Abstract

An 8-year-old, male Boxer was examined for an acute onset of ambulatory paraparesis. Neurologic examination was consistent with a T3-L3 myelopathy. Myelography revealed an extradural spinal cord compression in the region of the T10-T13 vertebrae. On magnetic resonance (MR) imaging, a well-defined epidural mass lesion was detected. The mass was mildly hyperintense on T1-weighted, hyperintense on T2-weighted and STIR images compared to normal spinal cord and enhanced strongly and homogenously. Postmortem examination confirmed a primary epidural hemangiosarcoma. Findings indicated that the MRI characteristics of spinal epidural hemangiosarcoma may mimic other lesions including meningioma and epidural hemorrhages/hematomas of non-neoplastic etiology.
